An all-caps alphabet (A–Z) plus numerals, shown in two styles – Doris-DBRH (solid) and Doris-DBRH Stencil – in Lettera 4 from 1972. The design is credited to Armin Haab, 1970 [Lettera 4].

The Stencil style appears to be based on the official Swiss norm SN 640 869 Bodenpfeile und Bodenschriften (‘arrows and typefaces for the ground’), which was digitized in 1999 by Masahiro Nakamura, see LL Asphalt and its sucessor, LL Pirelli.

Dan X. Solo showed a phototype adaptation as Whiteline Stencil [Stencil Alphabets: 100 Complete Fonts, 1988] which provided the basis for F37 Whiteline (F37, 2023).
